Video quality: Chromecast vs XBox Series X

[Eish]

I checked the quality of streaming content from different sources. chromecast looks - better, sound is softer and mufflier though. I thought these were zeros and ones, why do they look so different?

X Box Series X - 60Hz, SDR, 4K (originally HDR)

Chromecast with Google TV 60Hz, SDR, 4K (originally HDR)
